Losi LOSA6356 Shim Set Metric 5mm/6mm LST XXL LST/2 XXL-2 22 4.0

The Losi LOSA6356 is a metric shim set in 5mm and 6mm sizes, built for the LST, XXL, LST/2, XXL-2, and 22 4.0. Shims are thin spacers used to fine-tune the fit and alignment of rotating components like gears, bearings, and shafts, letting you dial in precise spacing that affects everything from gear mesh to differential preload.

Having a range of shim thicknesses on hand gives you the flexibility to make small adjustments during a rebuild or tuning session without guessing at spacing, which matters when you're trying to eliminate unwanted play or binding in a drivetrain component. This genuine Losi set matches the factory 5mm and 6mm specifications used across these platforms, so you always have the correct shim on hand for the job. Keep this set with your tuning tools to make precise adjustments whenever your build calls for them.
